This invention is concerned with improvements in machines for formingflanges on shoe uppers and has particular reference to machines forforming outwardly turned flanges around the heel ends of the shoe uppersand comprises upper clamping and flange forming devices. A known machineof this character is described in United States specification No.1,880,737.

One of the various objects of the present invention is to provide novelwork positioning means, in a machine having upper clamping and angeforming devices, which will be capable of positioning uppers of varioussizes Without changing any of the parts of said means.

Another of the various objects of the present invention is to providenovel power operated mechanism, in a machine having upper clamping andange forming devices, for operating such devices.

A machine, illustrative of the invention, which is hereinafter describedis provided with an upper gauging device for positioning an upper in themachine in relation to upper clamping and flange forming devices of themachine. The gauging device consists of two plates, pivoted to themachine frame, against which ,the edge of the'portion of the upper whichis to be turned outwardly to form the flange is positioned. The plateshave each formed in them one half of a U-shaped opening through whichopening the hanging device projects.

The edge of each part of the opening is held against the flanging deviceby a comparatively light spring so that the plates can swing outwardlyas the flanging device forms the outwardly turned flange and the platescan accommodate themselves to flanging devices of different sizes whichmay be used in the machine. It is therefore unnecessary to change theplates when the Hanging device is changed. Further, since the edges oithe opening are held, by the spring, against the ilanging device thereis no opening .between the plates and hanging device into which lthemargin of the upper might project when the upper is presented to themachine and its edge around the heel end portion is placed against upperat the heel end thereof. l

The illustrative machine is arranged to be operated by power mechanismwhich includes a crank and a toggle device so' arranged that as thetoggle of the toggle device is straightened the Vupper is clampedagainst the inside lformer and the crank causes, through thestraightened toggle, the upper to be more firmly clamped and the flangeto be formed on the upper.

' chine head l which is supported on a column or `base 3.

The machine head IV hasforined in it at the front of the machine anupwardly and rearwardly extending guideway 5. The guideway is at anangle of forty-live degrees to the horizontal and has slidinglylmountedv in it a cross-head The cross-head 'l is in the form of a plateabout eight inches wide and about seven inches long. The side edges ofthe crosshead' have extending from thein rectangular guides which engagein the guideway.'

The machine head I has formed in it a second jguideway 9, lying parallelto andinidway 'of the gudeway 5, in which is sliding'ly. mounted a slidemember II which carries an inside former I3.

The slide member II is about two inches wide. The slide member Il hasprojecting forwardly from it, about midway of its length, a headed pinI5 and at its upper end has extendingupwardly ber II and at its lowerend has formed in it an open-ended slot I9 into which the headed pinprojects. The rear face of the inside former I3 engages the slide memberIll and has an overhanging lip 2| which provides an upwardly extendinghorizontal recess at the rear of the in- 'side former. This recessengages the upwardly extending flange I1 on the slide member II. Byengaging the recess with the flange I1 and the open-ended slot I9 withthe pin I5 the inside former I3 may be easily placed on the slide memberII and by sliding the inside former upwardly to disengage the recessfrom the ange I1 and then moving it forwardly the inside former mayreadily be removed from the slide member I I and a different former maybe placed in theY machine. The upper end of the inside former I3 isshaped to correspond to the heel end portion of an upper which is to beoperated upon and has a plane rear face 23 lying parallel to theguideway 5 for the cross-head 1.

The headed pin I and flange I1 prevent the inside former I3 from movingforwardly and rearwardly and are arranged to allow the upper end of theinside former to rock slightly laterally. The slide member I I hassecured to its upper end, at the rear of the inside former I3 a camplate 25 (Figure 2) the upper end of which is normally held against astop face 21 on the machine head I by a compression spring 29 whichengages at its upper end the upper end of a bore in the slide member I Iand at its lower end engages a washer 3| which is engaged by the upperend of an adjustable screw 33 in the machine head I below the slidemember II. l

Pivotally supported on the cross-head 'I are a pair of outside formerswhich press the heel end portion of the upper against the inside formerI3. Each outside former comprises a block 35, 31 having anupper-engaging surface 39, 4I shaped to conform to about one half of theinside former I3 around its heel end and for some distance along theside of the inside former. The upperengaging face 4I on the right handblock 31 extends further round the heel end of the inside former I3 thanthe upper-engaging face 39 on the other block 35 with the result thatwhen the blocks are in engagement with the upper the Ajoint between thetwo blocks at the heel end of the upper lies to one side of a verticalplane passing lengthwise centrally through the inside former I3. Thisarrangement prevents the ex- I treme rear end of the upper, which mayhave on it a back strap, from being nipped or marked by the meetingedges of the faces 39, 4| on the blocks. 'Ihe rear faces of the blocksand the rear face 23 of the inside former all lie on the same planewhich is parallel to the guideway 5.

The blocks 35, 31 have projecting laterally from their outer side faceslugs 43, 43 which enter openings in block carriers 45, 41 and pins 49,49 passing through bores in the block carriers and lugs secure blocks totheir carrier. 'I'he pins 49, 49 have knurled heads formed on theirforward ends by which the pins may be readily withdrawn and then theblocks 35, 31 may easily be removed from their carriers 45, 41 and apair of blocks of a different size or shape may be secured to the blockcarriers, these blocks also having lugs projecting from them to enterthe openings in the carriers and holes to receive the pins. Theleft-hand block carrier 45 has projecting towards the right from itsupper end an arm 5| i having a, rounded end 53, the axis of which liesin the aforesaid vertical plane passing centrally through the insideformer I3, which engages a rounded recess formed in the upper end of theright-hand block carrier 41. The rounded end 53 of the arm 5| and therecess are held in engagement with each other by a tension spring 55which is connected to pi-ns 51 extending from the upper ends of thecarriers 45, 41. The pins 51 are secured in projections 59, 59 on thecarriers which extend upwardly, parallel to the guideway 5 for thecross-head 1, and enter a recess in the cross-head. The projections 59and recess prevent upward or downward movement, at right angles to theguideway, of the upper ends 0f the block carriers 45, 41.

'I'he upper end portions of the block carriers 45, 41 are connected tothe cross-head 1 by a pair of links 6|, 6| having rounded ends whichseat in corresponding recesses in the block carriers and cross-head.Pins pass through the links 6I and are secured in the block carriers 45,41 and cross-head 1. The links 6I extend upwardly and outwardly fromtheir pivotal connections to the block carriers at an angle of aboutthirty-ve degrees to the aforesaid vertical plane.

The block carriers have extending rearwardly and downwardly from theirupper end portions a pair of pins 63, 63 which enter open ended slots55, 65 formed in the side margins of the lower end of an upwardly andrearwardly extending slide 61. The pins 65, the pins in the lower endsof the links 6| and the rounded end 53 of the aforesaid arm 5I on theleft hand block carrier 45 all lie, when the cross-head 1 is in itsraised position, at about the same level heightwise of the machine.

The upper part of the slide 61 is guided in a guideway 69 formed in abracket 1| secured on the upper part of the machine head I. The slide 61has formed in it a slot 13 which extends lengthwise of the slide andpassing through the slot and slidingly mounted in a bore in the bracket1| is a headed pin 15, the head of which is pressed against the slide bya compression spring 11 between the machine head and a nut 19 threadedon the headed pin 15. Movement of the slide 61 in its guideway 69 is bythis means frictionally resisted.

The lower ends of the block carriers 45, 41 have pivoted to them by pins8|, 3| extending downwardly and rearwardly the upper ends of rods 83, 83which from their upper ends extend downwardly and forwardly and alsooutwardly laterally of the machine. 'I'he rods 83 are slidingly mountedin sleeve members 85, 85 which are pivoted at 81, 81 to the machine headI. The sleeve members 85 each have in them a compression spring 89 whichas the cross-head 1 is moved downwardly is engaged and compressed by thelower end of its rod 83. The cross-head 1 is normally held in a raisedposition in which the upper end of the cross-head 1 engages a face onthe bracket 1I by a pair of compression springs 9|, 9| one at each sideof the cross-head, in bores extending lengthwise of the cross-head. Thesprings 9|, 9| engage the ends of the bores and- 'plungers 93, 93 in thelower ends of the bores which engage studs 95, V projecting from themachine head.

As the cross-head 1 is moved downwardly in its guideway 5 by a treadleoperated mechanism inside former I3.

the arm 5| on the left-hand block carrier 45 until their lower endportions engage the side of the heel end portion ofan upper which hasbeen placed on the inside former |3. During continued downward movementof the cross-head 1 the blocks 35, 31 wipe the upper down the sides ofthe inside former |3 and the slide 61 also moves down but owing -to thefriction exerted on the slide the blocks 35, 31 swing inwardly as theymove down and press the upper against the sides of the inside former I3.As the crosshead 1 moves down the rods 83 which are pivoted to the lowerends of the block carriers 45, 41 move downwardly in and swing inwardlywith their sleeve members 85 but the lower ends of the rods do notengage the upper ends of the springs 89 in the sleeve members until theblocks 35, 31 have been moved down so far that the upper portions oftheir inner curved surface are pressed against the upper. The upperwhich has been placed on the inside former I3 is in this manner wipeddown and pressed against the inside former. As will hereinafter appearthe blocks 35, 31 are pressed more firmly and the ange is formed on theupper, by hanging members, by power operated means.

The upper anging members lie just behind the inside former I3 andcomprise a pair of flanging blocks 91, 99 which are arranged to spreadapart about a, common axis |9| (Figure 7) to form the flange on theupper. When the flangingblocks 91, 99 are closed together the edge ofthe front face of the blocks conforms in size andshape substantially tothe size and shape of the inside former I3. 'Ihe left-hand block 91(Figure 7) at its upper end has formed in it a cylindrically shapedrecess |03 extending inwardly from its front face, the wall of which isconcentric to the axis |I about which the blocks move and the right handblock 99 has projecting from its upper end a lug |05 which is shaped tofit into the recess |03, the forward face of the lug being acontinuation of the front face of the block. The outer edge of the righthand block extends, at the top of the block, to the left of theaforesaid vertical plane which passes centrally through the By thisarrangement a continuous edge is provided around the front face of theanging blocks which remains substantially unbroken as the flangingmembers are spread" apart.

Each flanging member 91, 99 is detachably secured to the front of aiianging arm |01, |09 the front faces of which arms lie parallel to theaforesaid guideway 5 for the cross-head 1, by pins I I I secured in eacharm and a hole in each flanging member and a forwardly and rearwardlyextending face ||3 on each flanging member and a face on a forwardly andupwardly extending ange I|5 on each arm. The left hand arm |01 hasextending downwardly and rearwardly from its `upper end at right anglesto the guideway 5 a sleeve ||1 which is rotatably mounted in a sleevebearing ||3 (Figure 2) on the machine head. rIhe right hand arm I 09 hasextending downwardly and rearwardly from its upper end a spindle I|9which is rotatably mounted in the aforesaid sleeve ||1 on the left handarm |01.

The spindle ||9 has secured on its rear end a washer |2| (Figure 2)which is larger in diameter than the sleeve ||1 and prevents relativemovement in one direction between the arms |01, |09. A face on the rearof the right hand arm |09 en- -gages the forward end of the sleeve andprevents 'relative movement between the arms |01, |09 in 75 the otherdirection. The washer |2| normally engages a shoulder at the rear of thesleeve bearing I8 and is held against the shoulder by a compressionspring |23 housed in a cylindrical chamber, coaxial with the axis of thesleeve and spindle, in the bearing H8. The rear end of the spring |23 isengaged by an adjustable screw |25, in the rear end of the chamber, bywhich the spring may be adjusted.

Each flanging arm |01, |09 has extending downwardly and rearwardly fromit near its lower end a pin |21 on which is rotatably mounted arectangular block |29. The blocks |29 engage in rectangular grooves |3I(Figure 3) in the aforesaid cam plate 25 which is secured on the slidemember which carries the inside former I3. The rectangular grooves 3|extend upwardly and outwardly at an angle of ninety degrees to eachother and the blocks |29 normally lie Vin the lower ends of the groovesclose towher'e the grooves meet.

The margin of the upper which is to be iianged outwardly, in theillustrative machine, is positioned rearwardly of the rear face of theinside former I3 by a pair of gauge plates |33 (Figures 2 and 3) thefront faces of which are as far rearwardly of the rear face of theinside former I3 as the width of the margin of the upper which is to beturned outwardly. Each plate |33'is pivoted at |35 at its upper end to ahead |31 on the forward end of a downwardly and rearwardly extendingstem |39 which is slidingly mounted in the machine head a little higherthan the aforesaid sleeve ||1 and spindle ||9 on the flanging arms. Thestem |39 extends downwardly and rearwardly at right angles to thecross-head guideway 5 and the pivots of the gauge plates are parallel tothe stem and lie one at each side of the stem. The gauge plates |33 areurged about their pivots, by a tension spring |4| connected at each endto the plates, towards the hanging members 91, 99. The lower portions ofthe gauge plates have in their inner edges recesses, the recess, whichis U-shaped, formed between the two plates extending around the top ofand along the sides of the hanging members 91, 99. The inner edges ofthe recesses in the gauge plates engage the bottoms of recesses |43(Figure 9) formed along the outer sides of the flanging members 91, 99.As the hanging members 91, 99 are spread apart to form the flange on theupper the gauge plates |33 swing with them about their pivots |35 and ifthe flanging members are changed for others of a different size theplates accommodate themselves to these members. Since the gauge platesare held by the spring |4| in engagement with the bottoms of therecesses |43 in the sides of the Hanging members they are always in aposition to be engaged by the edge of the upper when the latter ispresenetd to the machine.

The aforesaid stem 39 which extends downwardly and rearwardly from thehead |31 to which the gauge plates are pivoted has formed in the lefthand side of it a recess |45 into which projects an eccentric pin |41projecting from the right hand end of a horizontal shaft |49 which isrotatably mounted in the machine head I. The left hand end of the shaft|49 has secured on it outside the head a hand1ever 15| (Figure 1) bywhich the shaft may be rotated to adjust through the eccentric pin |41the stem |39 and gauge Vplates forwardly or rearwardly. The hand'lever-has in it a spring plunger arranged ltoenter one Yof a series ofrecesses|53 inthe machine head `sides of the eccentric links -|1|.

to hold the gauge plates in theiradiusted position and 'these recessesindicate to the operator'the .distance of theY front faces of thegaugecplates from the rear face of the inside former .and the width ofthe fiange which will be turned outwardly.

, The aforesaid cross-head 1 has secured in it studs |55 V(Figure 4)which have secured in their rear ends pins |51 on whichV are Ypivoted`the forward ends of a pair of parallel levers |59 which extend from thepivots rearwardly and downwardly. The studs |55 are secured in thecross-head near each side thereof. The rear ends of the parallel leversI 59 are pivoted to the upper ends of a pair of radius arms IBI whichare pivoted to the machine head I on horizontal coaxial pivots |53extending laterally of the machine. As the crosshead rises and falls thefront ends of the parallel levers |59 move in a straight path and theradi-us arms IBI swing forwardly and rearwardly. The parallel levers |59have pivoted to them, by horizontal coaxial pivots |95 extendinglaterally of the machine, the forward ends of a pair of rear- ,I1I forman inverted toggle which as will hereinafter appear in straightened bytreadle operated means before the driving shaft is caused vto beoperated.

A horizontal shaft |11 extending laterally of the machine is positioneda little rearward of the driving shaft |15 and is rotatably :mounted inthe machine head I. The shaft I11has secured on it a pair of upwardlyprojecting varms |19, the upper ends of which engage the rear Alsosecured on the latter shaft is a rearwardly extending karm I8| the rearend of which has secured in it a pin |83 which is arranged to be engaged:by

the upper end of a rod |85 connected to a treadle lever.

When the treadle lever is depressed the upwardly projecting arms |19engage the rear sides of the eccentric links |1| and swing the vlinksforwardly about the eccentrics |13, until the aforesaid shaft V|69 atthe upper ends of the eccentric links engages a stop face |81 on a block|89 which is secured on the machine head. As the eccentric links |1| arethus swung forwardly the toggle |61, |1I is straightened and theaforesaid parallel levers I59 are thereby swung downwardly about theirpivotal connections to the aforesaid radius arms ISI and move thecrosshead 1 downwardly to cause as -hereinbefore described the outsideformers to wipe down and clamp the upper against the inside former I3.

face controls the path of movement ofthe shaft |6| as the eccentricsrotate, and the front face of the plunger is only slightly greaterthanthe diameter of the shaft IBI. As the eccentric links I1I and cross-head1 are lowered by rotation of the eccentrics |13 the shaft I6-I movesdown between these faces which prevent the shaft IGI from movinglaterally during the rotation of the eccentrics and the toggle |61, |1Ifrom being broken. Should the eccentrics |13 be caused to be rotatedwhile the shaft |5| is above the plunger |9| the latter will yielddownwardly and thus prevent damage to the machine.

When the illustrative machine is in its normal stopping position theupper rounded end of the inside former I3 is a little higher than theupper round ends of the flanging blocks 91, 99 so that when the heel endportion of an upper is placed on the inside former I3 its margin canreadily pass rearwardly around the outside of the flanging blocks.

After the outside formers have pressed the heel end portion of the upperagainst the inside former |3 the driving shaft |15 is caused to berotated through a single cycle, by means hereinafter described, and thecross-head 1 is moved down and up again by the eccentrics |13. As thecross-head 1 is moved down by the eccentrics the aforesaid rods 83engage and compress the springs 89 in the aforesaid sleeve members 85and press inwardly the lower ends of the block carriers 45, 41 thusapplying further pressure upon the sides of the upper, the sleevemembers rotating inwardly and downwardly during this movement of thecrosshead 1. Also as the cross-head 1 moves down the inside former I3and the aforesaid cam plate 25 which is secured to the aforesaid slidemember II which carries the inside former I3 are moved downwardly andthe aforesaid rectangular grooves |3| in the cam plate cause theflanging members to swing outwardly away from each other. The downwardmovement of the inside former I3, relatively to the flanging blocks 91,99 causes the portion of the flange around the heelV end portion of theupper to be turned outwardly and the spreading apart of the flangingblocks 91, 99 causes the side portions of the ange to be turnedoutwardly. The rear faces of the inside and outside formers lie in thesame plane which is parallel to the crosshead guideway 5 and the frontfaces of the flanging blocks are positioned a slightly less distancebehind these rear faces than the thickness of the upper, and it may be astiffener in the upper, with the result that when the margin of theupper is bent outwardly the spring |23 which urges the flanging blocks91, 99 forwardly is compressed slightly and the flange is bent outwardlyparallel to and pressed between these faces.

The machine head I has secured to its left hand side a bracket |93(Figure 1) having a bearing for the left hand end of the driving shaft|15. The bracket |93 has in it a chamber and a worm-wheel |95 rotatablymounted on the driving shaft |15 and is housed in the chamber. Arearwardly extending horizontal worm-gear shaft |91 is rotatably mountedin a bearing |99 which projects rearwardly from the bracket |93.

The forward end of the worm-gear shaft |91 has secured on it a wormgear29| which meshes with the aforesaid worm-wheel |95 and the rear end ofthe shaft |91 has secured on it a pulley 1293. which is driven by a beltfrom a line-shaft Aor may be driven by other means.

The worm-wheel has in its left-hand side a recessj205 which is arrangedto be engaged by the right hand end of a bolt 201 (Figure 6) which isslidingly mounted in a. collar 209 which is secured on the driving shaft115. The bolt 201 is urged towards the worm-wheel by a spring 208 andits left hand end has on it a head 211 which is arranged to engage awedge face 213 on a block 215. The block 215 is pivoted at 211 to aclutch arm 219 and is normally held towards the ,path of movement of thehead 211 by a compression s pring 22| between the arm 219 and block 215.The block 215 has a downwardly extending lug 223 which enters a recess225 in the arm 219 and is held by the spring 221 against one side of therecess. When the head 211 of the bolt 201 engages the wedge face 213 onthe block 215, as the machine is being stopped, it swings the block 215about its pivot 211 until the block engages the arm 219. As the bolt 201thereafter travels along the wedge face 213 on the block it ispositively withdrawn from` the recess 205 in the worm-wheel 195. Just asthe bolt 201 is leaving the recess 205 in the worm-wheel 195 the spring221 overcomes the friction between the bolt and the recess and moves theblock 215 away from the arm 219 and causes the bolt 201 to be Withdrawnfrom the recess 205 in the wormwheel 195. This arrangement ensures thatthe bolt 201 is fully withdrawn from the recess 205 and preventsundesirable chattering between the bolt 201 and worm-wheel 195 which mayoccur if the bolt is not fully withdrawn.

The clutch arm 219 is pivoted on a horizontal stud 221 (Figures 1 and 5)secured in the bracket 193, which is lower than and rearward of thedriving shaft 115 and the arm 219 projects upwardly from the stud. Theupper end of thearm 219 is engaged by a shoulder 229 formed on` thelower side of a substantially horizontal latch arm 231.

The latch arm 231 extends over the upper end of the arm 219 and over thecollar 209 on the driving shaft 115. The latch arm 231 at its rear endis pivoted, by a horizontal pin 233 to the lower forked end of anupwardly extending arm 235 of a three-armed lever 231 which is securedon a horizontal laterally extending shaft Z39 which is rotatably mountedin the bracket 193. The lever 231 has extending forwardly from it an arm241 which, when depressed by the operator causes, through the shoulder239 on the latch arm 231, the arm 219 to be swung rearwardly to allowthe bolt 201 to be moved by the spring 208 into engagement with the lefthand side of the rotating worm wheel 195 and into the recess 205 in theworm wheel when the rel cess, during the rotation of the worm-wheel,moves into alignment with the bolt, When the bolt 201 has entered therecess 205 in the worm wheel 195 the driving shaft 115 is rotated andvduring an early part of the rotation of the driving shaft a cam face243 (Figure l) on the collar 209 raises the latch arm 231 and releasesthe shoulder 239 from the upper end of the arm 219. The arm 219 is thusallowed to be moved forwardly by a spring 245. connected to it and tothe bracket 193. into engagement with the collar and as the bolt 291travels round with the collar the wedge face 213 on the `block 215causes the bolt to be withdrawn from the recess in the worm wheel. Thedriving shaft 115 is thus disconnected from the continually rotatingworm-wheel 195 and may be finally stopped. if it has not previouslystopped after a single revolution by the engagement of the head 21 1with a shoulder 241 on the arm 219. When the arm 241 is releasedatension spring 249 (Figure 1) connected tovan arm 251 of thethree-armed lever 231 and to the bracket 193 raises the arm 241 andmoves the latch arm 231 forwardly so that its shoulder 229 will againengage the front face of the upper end of the arm 219. If the arm 241 isreleased immediately it has been depressed the arm 241 and latch arm 231will be returnedby the springV 249 and the arm 219 Will be movedforwardly by its spring 245 into engagement with the collar without theshoulder 229 on the latch arm 231 being disengaged from the arm 219 andthe latter will be raised and lowered idly bythe cam face on the collar209. i' g To prevent the driving shaft from being caused to be rotateduntil the aforesaid shaft 169 at the upper ends of the eccentric links111 has been moved fully forwardly and the toggle has been straightenedthe shaft 239 has projecting forwardly and upwardly from it a stop arm253 (Figure 1) which normally engages a hook 255 on a hooked lever 251which is pivoted on a horizontal laterally extending pivot 259 securedin the machine head 1 and prevents the arm 241 from being depressed. p

As the eccentric links 111 are swung forwardly, as hereinbeforedescribed by means of the treadle and just before they reach their fullyforward position, one of them engages an adjustable screw 261 in thehooked lever 251 and during the last portion of the forward movement ofthe eccentric links 111 moves the hook 255 on the hooked lever away fromthe stop arm 253 and thus allows the arm 241 to be depressed by theoperator. When the eccentric links 111 swing rearwardly the hooked lever251 swings rearwardly into a position in which its hook 255 is beneaththe stop arm 253 if the arm 241` has been released. If the arm 241 isreleased after the machine has been operated and the eccentric links111have moved rearwardly and have allowed the hooked lever 251 to moverearward therforward end of the stop arm 253 snaps past the hook 255which then moves beneath the stop arm.

The cam shaft 115 has secured on it a cam263 (shown in dot and dashlines in Figure 2) which during the rotation of the cam shaft 115engages the arm 255 of a bell-crank lever which is pivoted on ahorizontal laterally extending shaft 2115ecured in the machine head alittle lower than and forwardly of the driving shaft 115. Another arm219 of the latter bell-*crank lever extends forwardly beneath arearwardly extending lug 281 on the aforesaid slide member 11 whichcarries the inside former 13. The cam 263 is arranged to actuate thebellecrank lever just after the eccentric links 111 commence to rise andcauses the forwardly extending arm 219 of the bell-crank lever to engagethe rearwardly extending lug 281 on the slide member 11 and positivelyraise the slide member 11 somewhat; and with it the crosshead 1 andthus'assist the springs 29 `and 91 which normally raise the slide memberand crossaround the upper end of the inside former 13 with the edge ofits margin which is to be turned outlwardly against the gauge plates133, the gauge plates 133 having previously been adjusted forwardly orrearwardly according to the width of flange which it is desired to turnoutwardly. The operator then ldepresses the treadle lever and causes theoutside former to, wipe down-and clamp the heelend portion of the upperagainst the inside former I3. The operator thenwhile holding the treadledepressed, depresses the arm 24| andcauses the driving shaft |15 to makea single revolution, during which the outside formers are pressed morefirmly against the upper andthe outside formers and inside former aremoved down relatively to the flanging members. During the downwardmovement of the outside and inside formers the iianging members arespread apart and the ange is formed on the upper. The outside and insideformers are then raised by their springs and by the cam 263 andbell-crank lever and if the treadle is released the outside formers areraised to their highest position-and are opened.

Whenthe aforesaid shaft |69 has been swung to its forward position it ispositioned above the forward end portion of a lever 283 pivoted on astud 285 which is-securedin a bracket.281..se cured-on the head I..Therear end `portion of thelever 283is pivotally connected at 289 totheupper end portion of a link 29| .the.-lower end portion of which ispivotally connectedat 253 to an arm 2S5-which is pivoted onrtheAaforesaid shaftv |11. As the-shaft I ISS-is moveddownwardly Ybytheeccentric links- |1I it engages the forward portionofthe-lever 283 andmoves this portion downwardly, thus raising the rear end of the leverand throughthe link 29| swinging the arm 295 rearwardly. The arm 295carries a roll 291 which when the arm 295 is swung rearwardly engagesthe rod |85 and moves it away from'the pin |33. This enables the crosshead 1 to be fully raised as soon' as the driving shaft has completed arevolution even if the treadle lever is held depressed by the operator.

After the` eccentrics |13 have moved the cross head 1 down and havecompressed the spring 29 which supports the inside former I3 there maybe a tendencyv for the latter spring to suddenly raise the insideformer. I3 and cross head 1, as the eccentrics are moving in a directionto raise them, by rotating the driving shaft |15 through the togglelinks |1I and-eccentrics |13 and moving the bolti 201` ofthe clutch awayfrom the face of the recess which drives it. To prevent kthis theillustrative machine is DTOVded With a brake device (Figure 10) whichVcomprises an eccentric 299secured onthe driving shaft and a brakemember-30| which isarranged to-beengaged by the eccentric. The-eccentricis .arranged to engage the brakemember and tend to `retard rotation-ofthe driving shaft |15 during thatupart of themachine cycle-'whenthe-spring 29 whichsupport'sthe insideform'er vI 3v is expanding. andprel ventsthe spring from suddenly raising the inside formerandcros'shead.
